GPU Upgrade or not?

Hey guys I was wondering if you think this is a pretty decent upgrade for the price... I purchased a GTX 460 (768 MB) in August of 2010 right after the card was released and have been happy with its performance overall...but that was over 2.5 years ago and I am looking for a budget minded upgrade.

I found a sale for $90 at MicroCenter thanks to a link here... for a GTX 560 Ti 1gb. I have been looking at a few comparison websites and it seems like a pretty good jump in performance. I just want you guys to weigh in, the card is "refurbished" but I don't think that matters much, I buy a ton of stuff used on eBay and would buy a gpu off of there in a heart beat if I found a good deal.

Also, what exactly is the "Ti" I know its Titanium (I think) but whats the difference b/t the GTX 560 and the 560 Ti really?

From what I have read in a short amount of time it seems like this card would be quite a boost over my current 460 and I find $90 to be quite reasonable.

Your thoughts are very appreciated, you guys will dictate whether or not I purchase one of these tomorrow morning!

I assume you were not overclocking the 460 768MB but either way you should see a healthy increase in performance. The difference between the Ti and non-Ti is technically 384 shaders vs. 336 running at slightly faster clocks. 90$ sounds great if you're confortable with refurbished.
